Variable structure control for three-phase LCL-filtered inverters using a reduced converter model
Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Hoz Casas, Jordi de la (Institute of Electrical and Electronics Engineers (IEEE), 2017-06-16)
Article
Accés obertThis paper presents a new concept in active damping techniques using a reduced model of a LCL-filtered grid connected inverter. The presence of the LCL filter complicates the design of the inverter control scheme, particularly ... -
Variable structure control in natural frame for three-phase grid-connected inverters with LCL filter
Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Martín Cañadas, María Elena (2017-07-05)
Article
Accés obertThis paper presents a variable structure control in natural frame for a three-phase voltage source inverter. The proposed control method is based on modifying the converter model in natural reference frame, preserving the ... -
Variations of the Gauss Seidel and the gauss implicit z-bus load flow methods for primary-secondary integrated distribution grids
Barrenechea Gruber, Roberto Carlos; García de Vicuña Muñoz de la Nava, José Luis; Castilla Fernández, Miguel; Rypin, Federico; Paiva Mata, Pedro (Elsevier, 2022-09)
Article
Accés restringit per política de l'editorialThe primary and secondary distribution grids are typically designed separately and operated with a radial configuration; therefore, specialized load flow methods only applicable to radial or weakly meshed networks are ... -
Voltage sag mitigation in a PV-based industrial microgrid during grid faults
Ghahderijani, Mohammad Moradi; Castilla Fernández, Miguel; García de Vicuña Muñoz de la Nava, José Luis; Camacho Santiago, Antonio; Torres Martínez, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThe growing interests in industrial microgrid and its high power rating, have made it as a good candidate for voltage support purposes. The aim of this paper is to present a reactive current injection control strategy for ... -
Voltage security in AC microgrids: A power flow-based approach considering droopcontrolled inverters
Souza, Antonio Carlos Zambroni de; Santos, Marcos; Castilla Fernández, Miguel; Miret Tomàs, Jaume; García de Vicuña Muñoz de la Nava, José Luis; Marujo, Diogo (2015-01-01)
Article
Accés obertThis study deals with the problem of voltage security in microgrids. In general, voltage security is an issue for power systems, where the lack of reactive power is a concern. For microgrids a complexity is imposed, since ... -
Voltage support control strategies for static synchronous compensators under unbalanced voltage sags
Castilla Fernández, Miguel; Miret Tomàs, Jaume; Camacho Santiago, Antonio; Matas Alcalá, José; García de Vicuña Muñoz de la Nava, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 2014)
Article
Accés restringit per política de l'editorialStatic synchronous compensators have been broadly employed for the provision of electrical ac network services, which include voltage regulation, network balance, and stability improvement. Several studies of such ... -
Voltage support provided by three-phase three-wire inverters with independent reactive phase-current injection
Iñiguez Amigot, José Ignacio; Duarte Mejia, Josue Neftali; Camacho Santiago, Antonio; Miret Tomàs, Jaume; Castilla Fernández, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2024)
Article
Accés obertDuring voltage sags, three-phase three-wire power inverters can provide voltage support with several current injection strategies. In general, good results are ob- tained, except in overvoltage situations when one or more ... -
Voltage support using electric vehicles in an islanded resistive-microgrid under voltage sags
Miret Tomàs, Jaume; Castilla Fernández, Miguel; Borrell Sanz, Àngel (2022)
Text en actes de congrés
Accés restringit per política de l'editorialThe number of electric vehicles connected to the grid is growing constantly due to environmental and regulatory issues. Conventionally these vehicles work as variable loads, although using them as distributed generators ...
